Description

When factory components can no longer handle the power, Aeroflow Performance billet crankshafts step in to provide the ultimate foundation for high-horsepower race engines. Manufactured from premium 4340 billet steel, these crankshafts deliver maximum structural integrity and exceptional fatigue resistance, making them far superior to cast or forged options. To ensure longevity under race conditions, each crankshaft undergoes a precision deep-case nitriding process for maximum surface hardness and wear resistance. Finished with a final grind to ensure perfect balance and ultimate durability down the track.
